Mixing Copper Nanoparticles and ZnO Nanocrystals: A Route towards Understanding the Hydrogenation of CO2 to Methanol?

The shape of things to come: The preparation and combination of nanoparticles of copper and zinc oxide with controlled morphology opens new avenues in the understanding of metal–support interactions and may help resolving the intricacy of methanol synthesis during the hydrogenation of CO2. The improved selectivity to methanol formation observed with some of the morphology combinations suggests that the reverse water–gas-shift side-reaction to give CO could be dramatically minimized (see scheme).
